Hi Razvan
Hi Paul
OK it is frustrating that it seams so difficult to find users of the Tegam 1830 A
Over the next few weeks I would like to get onto the Tegam forum so you might possibly send the link you have to me
The link is not existing anymore. It was available on the old Tegam website but it seems that Advanced Energy, the new owner of Tegam, migrated them to the new website. For me the link was not working anyway, probably the forum was already closed when I tried it?!
Regarding calibration have you down loaded the user's manual ?? As from that it seems that the user can calibrate the Tegam 1830 A using standard Dc lab standards
Advanced Energy provides the manuals and other docs for the 1830A except the firmware. If you manage to get the firmware please let me know.
Manual link:
Other Technical docs:
Procedure to calibrate it is simple if you have the 3 items that they mention in the manual.
To initiate the calibration you need to connect to the power meter via ethernet port and there is a menu for calibration and verification in the webUI. Seems to be straight forward.
I think I will also have to try and contact a few Calibration houses in the UK
If they are 17025 accredited labs you can check online their accreditation to see what standards they use for the "RF Power Measurements". I checked last year a few cal labs in the EU and none of them had any Tegam stuff. They had Keysight and R&S power meters and sensors and probably they will do a comparison with their calibrated power sensor head in a setup similar to the one in Jeremy's photo. They normally use a software to do that fast and also compute all data in a report and print a new label for you or update the cal table in the EEPROM via software.
Check out Cal Lab Solutions, they have a software called PS-Cal that supports the Tegam hardware.
